Description

The gas pressure regulator, governor balance composite structure of floating
Technical field
The present invention relates to a kind of gas-fired equipment, relate in particular to the unsteady composite structure of a kind of gas pressure regulator, governor balance.
Background technique
Pressure governor is a kind of device that is used for regulating gas pipeline pressure, is provided with valve port pad that cooperatively interacts with it on the valve port of pressure governor.Be can produce certain pressure at valve port place at valve closing, be unfavorable for the operation of pressure governor.Meanwhile, existing valve port pad position is changeless, and due to machining accuracy, can to cause valve port valve port to level up face not parallel, will cause like this shape between valve port pad and valve port plane to have a certain degree, overpressure also can cause valve closing time.
Summary of the invention
Technical problem to be solved by this invention is: a kind of gas pressure regulator, governor balance composite structure of floating that can equilibrium valve mouth pressure is provided.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: the gas pressure regulator, governor balance composite structure of floating, comprise: valve body, be arranged on the valve rod in valve body, be arranged on the valve port seat of the valve inner of valve rod lower end, be arranged on valve and the gasket seal of valve rod lower end by fastening screw nut and cushion block, be provided with valve port pressure chamber in the inside of described valve port seat, in described valve body, the both sides of valve port seat are respectively arranged with suction port and air outlet, on described valve rod, be provided with piston, spring, sliding sleeve saddle, piston bushing, balance pressing plate, balance gasket, balance epithelium and balance briquetting, between described piston bushing and valve rod and balance gasket, be provided with balance pressure chamber, between described valve rod and sliding sleeve saddle, be provided with passage, described suction port is connected with described balance pressure chamber by passage.Be provided with cone seal piece matches with described gasket seal in the lower end of described valve port seat.
Advantage of the present invention is: the above-mentioned gas pressure regulator, governor balance composite structure of floating, can offset valve port pressure, can offset the valve port and the not parallel deviation of valve port pad that cause due to machining accuracy, make valve port pad keep remaining parallel with valve port plane, thereby ensure that pressure governor cuts out stable performance.
Brief description of the drawings
Fig. 1 is the structural representation of the unsteady composite structure of gas pressure regulator, governor balance of the present invention.
In figure: 1, valve body, 2, valve rod, 3, valve port seat, 4, fastening screw nut, 5, cushion block, 6, valve, 7, gasket seal, 8, valve port pressure chamber, 9, suction port, 10, air outlet, 11, piston, 12, spring, 13, sliding sleeve saddle, 14, piston bushing, 15, balance pressing plate, 16, balance gasket, 17, balance epithelium, 18, balance briquetting, 19, balance pressure chamber, 20, passage, 21, cone seal piece.
Embodiment
Describe in detail particular content of the present invention below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the gas pressure regulator, governor balance composite structure of floating, comprise: valve body 1, be arranged on the valve rod 2 in valve body 1, be arranged on the valve port seat 3 of valve body 1 inside of valve rod 2 lower ends, be arranged on valve 6 and the gasket seal 7 of valve rod 2 lower ends by fastening screw nut 4 and cushion block 5, be provided with valve port pressure chamber 8 in the inside of described valve port seat 3, both sides at the interior valve port seat 3 of described valve body 1 are respectively arranged with suction port 9 and air outlet 10, on described valve rod 2, be provided with piston 11, spring 12, sliding sleeve saddle 13, piston bushing 14, balance pressing plate 15, balance gasket 16, balance epithelium 17 and balance briquetting 18, between described piston bushing 14 and valve rod 2 and balance gasket 16, be provided with balance pressure chamber 19, between described valve rod 2 and sliding sleeve saddle 13, be provided with passage 20, described suction port 9 is connected with described balance pressure chamber 19 by passage 20, be provided with cone seal piece 21 matches with described gasket seal 7 in the lower end of described valve port seat 3.
As shown in Figure 1, the above-mentioned gas pressure regulator, governor balance composite structure of floating, when valve closing, inlet pressure P enters by the passage 20 between sliding sleeve saddle 13 and valve rod 2 that balance pressure chamber 19 acts on balance gasket 16, balance epithelium 17 belows produce power F2 upwards, and this power has been offset inlet pressure P and acted on the interior valve 6 of valve port pressure chamber 8 and produce downward directed force F 1.In addition, be provided with cone seal piece 21 in the lower end of described valve port seat 3 and match with described gasket seal 7, even if valve rod 2 positions have skew also can not affect the performance of closing of valve 6 and valve port seat 3 like this.
The above-mentioned gas pressure regulator, governor balance composite structure of floating, can offset valve port pressure, can offset the valve port and the not parallel deviation of valve port pad that cause due to machining accuracy, make valve port pad keep remaining parallel with valve port plane, thereby ensure that pressure governor cuts out stable performance.
